Kai's verdictS-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Still early. Manus is more flexible for less money.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
